<div class="post">
<p>In Groovy we have several ways to achieve the same thing. For example we can apply a method to all elements in a list with the <code>collect()</code> method or with <code>*.</code>.</p><pre class="brush:groovy">class User { 
    String name 
    String aloud() { name.toUpperCase() }
    String toString() { name }
}

def users = [new User(name: 'mrhaki'), new User(name: 'hubert')]

assert ['mrhaki', 'hubert'] == users*.toString()
assert ['MRHAKI', 'HUBERT'] == users*.aloud()
assert ['mrhaki', 'hubert'] == users.collect { it.toString() }
assert ['MRHAKI', 'HUBERT'] == users.collect { it.aloud() }
